Q:Does the heater control valve anything to do with the A/C ?My heater control valve needs replacing, as it leaks when I put my truck's heat on. No heat, no leak. I have to periodically re-add Prestone every once in awhile after using the heat . I've checked the valve and it only leaks when I have my heat on, if I don't use my heat, I don't lose fluid. But now I'm wondering if I use my truck's A/C, does the heater control valve have anything to do with the radiator fluid, or just the freon? Thanks in advanceCar Mechanic in training: Honda guy has the excellent answer, yet I actually have a pair issues to characteristic. whether it truly is like my daughter's 1993 Accord, it truly is extra straightforward to do from under the motor vehicle than above it. if so the converter warmth preserve is interior of reach and it badly cut back my wrist whilst i attempted to get the valve hose off the heater middle - positioned a rag on that depraved element. Be very comfortable mutually as wrestling the hose off the heater middle pipe that sticks with the aid of the firewall - the pipe is skinny brass and truly deformed. it truly is great to cut back the hose lengthwise and peel it off, and wait and notice. you will want to alter that little bit of hose besides. EDIT - one extra element. After refilling the coolant, locate the nipple (probable on the thermostat housing) for bleeding the trapped air out of the cooling gadget. Open it 0.5 a turn and close it whilst a comfortable flow of coolant comes out. ultimate up the radiator - undergo in suggestions, consistently use perfect coolant diluted in accordance to instructions with purified water, on no account faucet water. existence is physically powerful.

Q:How come my boiler supply valve isnt letting water into my boiler, i have a cold water supply hooked up to it with the valve on i have tested the copper pipe goin into it and water flows into it, but when It reaches the valve it stops. I understand that it my have a backflow preventer in it and I am wondering if that could be malfunctioning. The hole you see on the front is where my expansion tank screws in. Also where could I get a new Valve. Thanks.http://img149.imageshack.us/i/boilerfillvalve.jpg/: I work on antique steam boilers and engines for a hobby and if your supply valve isn't letting feedwater into the boiler, I'm going to tell you right now that you potentially have a VERY dangerous situation on your hands. Until you get this issue resolved, I would recommend that you not steam this boiler up under any circumstances, unless you have a backup feedwater delivery system that is working correctly. Many people don't know this, but a low water condition in a boiler under steam is essentially a ticking time bomb and can result in a fatal explosion. As to what may be causing it, I would say it's possibly one of two things: 1.) The check valve has been installed backwards and the flow of water is basically pushing it shut. 2.) The check valve is installed correctly, but is frozen shut due to corrosion and scale. Either way, I would have a certified boiler inspector come out and take a look at it; he can probably tell you more than I can.

Q:The time has come to re shim my 06 450, and I am having a small problem (I think anyway). The exhaust valves have decreased to below the required spec and need to be replaced with thinner shims (as is usually the case), but the left intake valve has for some reason increased its valve clearance (from 0.16mm to 0.23mm). Is it normal for the valve clearance to increase? I thought they would only decrease... Any ideas? Unless the valve is being held open by something. Many thanks, Jim: You want to do a clearance do you? Blow up the car.

Q:What are the names of the main arteries and valves?????????REALLY NEED ANSWERS TODAY!!!!!!!!!!!: Main arteries: Aorta (oxygenated blood from heart to body), Pulmonary Artery (DEoxygenated blood from heart to lungs). Main Valves: Tricuspid valve (separated right atrium and ventricle to ensure correct flow of blood), Bicuspid Valve( separates left atrium and ventricle), Aortic Valve( ensures blood flow from left ventricle into aorta). hey sorry only saw ur question today:P hope it helps!

Q:what exactly is thc pcv valve and what does it do: PCV stands for positive crankcase ventilator all engines need this device to work properly

Q:I have a 2001 Ford Ranger with a 4.0 V6. I recently broke the valve cover bolt on the top right hand corner of the passenger valve cover ( the bolt closest to the belt). 1. Can I drive it like this and since 7 of the 8 bolts are in it should it leak worse. 2. How do I fix it, and 3. How much would this cost to have fixed if I took it somewhere. Thanks for your help: Yes you can drive the vehicle with 1 broken bolt to the valve cover. The valve cover should leak a little due to the lack of tension at the broken bolt. The leak may be minimal. If you remove the valve cover use silicone as a new gasket, you can use extra silicone at the broken bolt. Allow the silicone to dry before tightening the valve cover bolts. The extra silicone may stop any oil to blow by the broken bolt problem solved. The valve cover does nothing more than stopping oil from leaking. A leaky valve cover nothing more than leak will not affect how the vehicle runs. The cost to have the broken bolt replaced should be around $100.00 (if the broken bolt is accessible) The cost is strictly labor (time). About $100.00/an hour. To repair this you have 3 options; 1) You can extract the bolt. This may be very easy depending on the accessibility (can you get a drill over the broken bolt?). If you can drill a whole in the broken bolt, you can lightly tap an extractor into the whole with a hammer. Then with a wrench or a pipe wrench you can try to extract the bolt by turning the extractor counter clockwise. Use WD40 or a catalyst to loosen the broken bolt. The longer the catalyst (WD40) has to work the better. ie- spray the broken bolt 3 or 4 times a day allow the oil time to loosen the broken bolt. You can purchase extractors at any auto parts store for about $15.00 I can't emphasize the importance of WD40 enough!!!! 2) The 2nd option is to use a healy coil. You would need to drill out the bolt to a specific size (the healy coil package will tell you what size drill bit to use). After drilling out the bolt you can insert a healy coil that will allow you to use the same size bolt you just drilled out. The healy coil package will have detailed instructions. This is very easy to do! Healy coils can hold a lot more torque than valve covers require. 3) The third option is to drill out the broken bolt completely tap new threads insert a larger bolt.

Q:Hello,I've not found a perfect fit using a solenoid valve for gravity fed irrigation system. Primarily because it requires a constant drain on the battery while the valve is open. Is there a motorized valve to fit the bill? One that momentarily requires electricity to open and close the valve at 12v DC or less to work in gravity fed system?: I don't know how it specifically wires. There are two strategies for latching devices. One is a solenoid with two coils. Pulse one to open, pulse the other to close. The other strategy is to have one coil. Apply polarity in one direction to open, in the other to close. I suggest googling for latching solenoid valve, and/or checking out the major irrigation (or sprinkler) manufacturers for their offerings.

Q:ok...i want to find a valve that controls air pressure so i can let it out in 2 different ways for my pneumatic potato gunwhat websites or stores sell this (not home depot): You might have to register on the site to order online. It is free. You can call them and order the catalog. It is free also. Hope this helps Email me if you want me to look it up in my catalog. Don't break any windows. Wingman

Q:Is a Head gasket the same thing as the valve cover gasket, on my honda civic si?: LOL. No. You don't get away that easily. The valve cover gasket only keeps oil from splashing all over the engine bay. It literally covers the valves, sealing the engine interior away from the general environment. Th head is the part of the engine that the valve cover sits on. It contains the valves, and either the camshaft or the rods that lead to a camshaft deeper in the engine, and of course the rocker assembly. You have to remove all those big bolts along the casting to break the head free, and you'll need a torque wrench to get the pressure right when you're reinstalling it. The head gasket seals the tops of the cylinders [incorporated in the bottom of the head] to the cylinders themselves [bored into the block proper.] Have fun!!!!!

Q:i dont get how valves produce the sound? and why did we change to solid state? was that because they we're used in stereos?: Most valve amps I have used reproduce the sound of a tube amp. Tubes have a warm sound and can be overdriven to get that good rock crunch distortion sound. We went to solid state because they were durable and didn't require the maintenance of a tube amp. Printed circuits and transistors cut the cost of manufacturing. The old tube amps still have the purpose and they never quite matched the exact sound of tubes with the solid state amps. That is why they are making a lot of tube amps now.
